Facebook has sent out invites to the press in the US for a ‘mobile event’ on Wednesday. The event is being held barely a month after rumours of Facebook launching its own phone. So will we really see Facebook releasing its own hardware or will it be just a tie-up with a handset vendor like INQ? Or is this not about hardware at all and we are simply looking at some new mobile-centric feature? All will be revealed on Wednesday, that is if someone does not leak it earlier. We are counting on the latter.
